Cryogenic Focus Mechanism

Motiv Space Systems is proposing the development of anbsp;Cryogenic Focus Mechanism (CFM) fornbsp;planetary cameras operating in extreme cold environments. The focus mechanism is intended to augment typical fixed focus cameras or spectrometersnbsp;which are commonly integrated into NASA rovers and landers. The provision of a variable focus mechanism will enable greater contextual imagerynbsp;for future Navcams, Hazcams, robotic workspace cameras, sample inspection instruments, and any othernbsp;applications addressed by the current fixed focus imagers. The intent is to package annbsp;actuatednbsp;focus mechanism within typicalnbsp;volume constraints of fixed focus lens assembliesnbsp;tonbsp;promote seamless adoption and integration. The mechanism will be designed to operate at temperatures of -180C which will mean it will not need additional thermal resources.nbsp; Anbsp;mechanism design will be completed utilizing Mars heritage practices and validated by anbsp;feasibility Code V analysis of the opto-mechanical lens arrangements.nbsp;
